Process of manufacturing metallic coated products

or a layer of celluloid or cellophane. To illustrate, 1f I use a fabric material as my such as muslin or broadcloth, and treat this fabric with foil, durable, airtight, In addition, the finished product can be emossed with designs such as birds, animals, reptiles, to represent leather, and can be obtained in a variety of colors. If I use tin be had with the exception that the finished product will not be reproof.

A muslin fabricand my adhesive, plus a layer of aluminum foil results in an excellent Y by celluloid, will non-inflammable fabric which can be used for upholstery, electrical condensers, handbags, suitcases, shoes, slippers, book-binding, and as an aeroplane clothfor wings, etc. By employing a manila paper base, treating the paper with the adhesive solution, and then applying the metal foil, aluminum, many interesting applications may be made h as boxes, plates, table covers, etc.

If desired, the paper or muslin base can be treated with the adhesive and then coated or celluloid. If further desired, muslin or with the adhesive and then the metallic foil hereupon a second layer of muslin ductor of electricity good for condensers and cables, and which is particularly suitable for use in tents, awnings, etc., because of its waterproofing qualities.- A similar combination of materials, but replacing the metal foil result in a fabric which can be employed in constructing bullet proof vests, pads or other articles.

In carrying out my process I take one pound of' pure para gum (india rubber), the

, adhesive is to apply to the adh of the cloth, a layer of preferably broadclothcan be treated finest grade and free of um is heated in a keti. When the gum is heated to this degree 0 heat, I now add one pound of mineral oil. The mixture of oil and gum is thoroughly stirred and allowed to boil for one-half hour at theafore-mentioned temperature, whereupon the oil dissolves the rubber. Th

esive solution which is roperties. Next, take the material to be treated for example broadcloth and i and apply the adhesive solution to the broadcloth while it is still warm. The solution of adhesive penetrates the fibres of the cloth and deposits thereon a fine layer of adhesive. The cloth with this fine adhesive coating is allowed to cool. The adhesive coating upon the cloth has cooled, esive surface coating aluminum foil of .005 in thickness. If desired, the metal can be first cleaned with an alcoholic solution of hydrochloric acid. The foil adheres readily to the adhesive surface of the cloth, Whereupon the combined fabric and foil are thru rollers, to eliminate any air bubbles and surplus adhesive.

gum must be of the all impurities. This tle to 302 F. (150 the base tion of the base. Furthermore, thisis important, if any of the ordinary glues or adhesives were to be used in a combination such as I prop product absolutely unfit for the many uses whic I propose for my invention.

ile I havedescribed my process as adaptable to paper or fabric, I do not limit it can be readily seen that the same result grees F. for about one half hour, allowing the solution to cool on the fabric and applying thereto a layer of metallic foil.

What I claim is:

1. A process of manufacturing a product having a fabric base, consisting in applying while it is still warm an adhesive solution composed of india rubber and mineral oil which have previously been boiled together 19 at a temperature of approximately degrees F. for about one half hour, allowing the solution to cool on the fabric and applying thereto a layer of aluminum foil oi approximately .005 in thickness.
